Development of MRI Projection Mapping System for Breast-Conserving Surgery in the Operating Room: Preliminary Clinical Results in Invasive Breast Cancer

Figure 1

Patient positioning. (a) Contrast-enhanced breast MRI is performed with the patient in a supine position. The arms of the patient are raised using Vac-Lok™ cushions (black arrow) to reproduce their position on the operating table. A home-made tilting table with a 15° slope (white arrow) is set under the back of the patient with breast cancer in the outer breast region. (b) Markers are put on the rigid chest walls. Adalat capsules are hyperintense on contrast-enhanced fat-suppressed T1-weighted images.
